SPECIFICATION forming part of Letters Patent No. 310,587, dated January13, 1885. Application filed April 18, 188-1. (N model.)

To (LZZ whom it may concern:

Be it known that I, GEORGE M. HATHA- \VAY, a citizen of the UnitedStates, residing at New York, in the county of NewYork and State of NewYork, have invented certain new and useful Improvements inPrinting-Telegraphs, of which the following is a specification,reference being had therein to the accom: panying drawings.

My invention relates to a printing-telegraph system and apparatus of theclass in which rotating type-wheels are used in connection withimpression devices operated by electromagnets, the objects of theimprovement being to accomplish the transmission of printed telegraphicmessages with increased rapidity as compared with thepreviously-existing state of the art, to print at thetransmitting-station a message simultaneously withits transmission to areceiving-station, and to print messages in pages of parallel lines,though the apparatus maybe used for printing in a continuous line on anarrow strip or fillet.

The invention consists in the improved system and the apparatuscomprising certain novel constructions and combinations of devices,which will be hereinafter particularly described, and pointed outin theappended claims, reference being made to the accompanying drawings, inwhich- Figure]. is a side elevation of a printingtelegraph apparatusconstructed and arranged :for operation according to my invention. Fig.2 is a side elevation of the transmitting apparatus. Fig. 3 is atop viewof the same. Fig. & is a front view. Fig. 5 is a vertical section on theline 00 x of Fig. 2. Fig. 6 is a horizontal section 011 the line y-g ofFig. 2. Fig. 71s a side elevation of the receiving apparatus. Fig. 8 isa horizontal section of the same on line a" .r of Fig. 7. Fig. 9 is adetail top view illustrating the devices for releasing and arresting thetype-wheel of the transmitting apparatus and for closing the circuitthrough its printing-magnet.

Fig. 10 is a view, partly top board and base of the supporting-frame,the top board being supported by suitable posts or pillars, B B,standing on the base.

Between the front posts, B, is supported a cross-piece, 0, upon theunder side of which is secured a metallic plate, D, having near itsmargin an annular series of perforations, d, coinciding with similarperforations in the cross-piece O.

In the perforations of the cross-piece and metallic plate D are arrangedmetallic pins E, the upper ends of which are pivoted, respect ively, tothe ends of key-levers .F, the outer ends of which are pivoted tosupports f, secured to the under side of the top board, A. Through thistop board are perforations, in which are loosely arranged pins g, havingtheir lower ends pivoted to the levers F, respectively, while theirupper-ends, above the top board, are provided with heads or fingerpiecesG, between which and the top board are arranged spiral springs g, forholding up the pins and the levers F. The pins and their heads form thekeys for operating the levers F, which normally are held up by thesprings against a stop, F, so that the lower ends of the pins E will notlie plate D.

In a perforation, e, of the metallic plate D is arranged a pin, E, ofnon-conducting rna- 8o terial, having its upper end pivoted to the innerend of a lever, H, which is pivoted to one of the posts B, and has itsouter end secured to a segmental bar, H, which lies under and againstthe levers F, and is pressed upward 8 5 by a spring, h, Fig. 2. It willnow be seen that if either one of the levers F is pressed downward byits key the metallic pin E, attached to said lever, will be pressed downthrough and beyond the metallic plate D, and 0 at the same time the saidlever F will act. on the segmental bar H, to cause the inner end of thelever 11 to be raised and draw up the nonconducting pin E, whichnormally projects below the metallic plate D.

Through the center of the metallic plate D and cross-piece O is anopening, through whiclr is arranged a vertical shaft, 1, the lower endof which has a bearing in a step, i, on the base board, while its upperend projects rcc project below the n1etalconnected to a barrel, Lconnected with the train L, for driving the same in an ordinary manner.

To the shaft I, directly under the metallic plate D, is secured a radialmetallic arm, M, (see Figs. 4 and 6,) projecting outwardly a lit tlebeyond the perforations in said plate, so that if revolved it willstrike the non-conducting pin E when said pin projects below the plateD, and if this pin is drawn out of its path the arm will strike any pinE which may be projected below the plate. The shaft I has normally atendency to rotate under stress of the train L, and so the arm Mordinarily rests against pin E, and when a key-lever and its pin E isdepressed the pin IE will be raised and release the arm M, which thenflies around and strikes the depressed pin E.

Just above the pinion Z on the shaft I a circuit-breaking wheeLN, isfixed upon the shaft, and against its periphery bear two metallicfriction-wheels, a or, carried by spring-arms N N, which are secured tothe downwardlyprojecting ends of two binding-posts, N N", arranged uponthe cross-piece O. The makes or metallic spaces in the periphery of thecircuit-breaking wheel are the same in number and coincide in positionwith the characters on the type-wheel, as do also the metallic pins E,each of which represents a letter or other character. A binding-post, Nis electrically connected with an arm or lateral extension, d, of theplate D, and from this post N" a wire, 10, leads to the printing-magnet,as will pres- .ently be more particularly described.

Pis the printing-magnet of the transmitter. It is mounted upon the upperend of a tubular post, p, the lower end of which rests upon a bracket,Q, depending from the base-board. (See Fig. 1.) The armature-lever p ofthis magnet extends upward, and carries a printing-pad, p arranged todrive the paper against the typewheel when the magnet attracts thearmature.

Above the magnet l is a plate, 1), projecting from the front end of thetop board, A, and having a circular opening, through which the upper orpad end of the armature-lever projects. Vithin this circular aperturefits a flange, 0, Figs. 6 and 10, projecting from a ratchet-wheel, R,which lies upon the plate 12". Below the magnet, upon its tubularsupporting-post p, is a sleeve, Q", the lower edge of which is arrangedto bear against a pin, q, projecting from the post. A lug, g, beveled orinclined on one edge, projects from the lower edge of the sleeve, andwhen said sleeve is rotated in the proper direction, and the inclinededge of the lug comes in contact with the pin, it will ride upward oversaid pin, forcing up the sleeve, which will fall back by gravity whenthe lug has passed the pin.

From the sleeve Q spring-arms S stand out and extend upward through theratchet-wheel R, and bear outward against its inner periplr cry. Thesearms have on their surfaces next the wheel slight upwardly-inclinedserrations s, and there are similar serrations, s, on the innerperiphery of the wheel. From the sleeve project arms q g, which supporta reel, g", which carries the paper T. Thepaper T is to be led upthrough the ratchet-wheel R, and formed into a tube around thespring-arms, S.

As before stated,the wirew leads from binding-post N to onecoil-terminal of the print ing-magnet P,passing up through the tubularsupporting-post, and from the other coil-terminal a wire, w, leads toone pole of supplement-ary battery X, which has its other pole connectedto ground. From one pole of the main battery, as at X, a wire, leads tobinding-post N", and the line-wire V is connected to post N. Thebatteries X and X have similar poles to the ground.

The operation of the printilag-transmitter, as now described,is asfollows: \Vhen the circuit-breaking and type wheels are at unisonagainst pin E, and at this time the frictioncontact rollers bear againstmakes or con ducting portions of the break-wheel, a key is depressed anda metallic pin, I forced down through the plate I), the arm M, beingreleased, flies around and strikes the depressed metallic pin, and thetype-wheel is arrested with that letter or character opposite theprinting-pad which is represented bythe depressed pin. At this momentthe main circuit is closed through the break-wheel, and the circuit ofsupplementary battery X is closed through the printing-magnet to theline, owing to the fact that electrical connection is now made from postN through extension d, plate D, the depressed pin E, which the arm Mforces in contact with said plate, through said arm M and the shaft I,to the break-wheel and springarm N, supported by post N, and which has aroller on a make of said break-wheel. The printing-magnet is thusenergized and operates its armature-leverto force the paper against theletter of the type-wheel when opposite the printing-pad. \Vhen the pin Eis allowed to rise, the circuit through the printing-magnet is brokenand the arm M continues its movement quickly till it again strikes theunison-pin E, which is then depressed by spring 71. When the shaft Ibegins its move ment after the arm M is released by the unison-pin, alug, i", projecting from the shaft I, strikes a shoulder, a, on a slide,U, arranged on aplate, p, and drives said slide endwise against theforce of a retracting-spring, a. The slide U carries a spring-pawl, awhich at each forward movement of the slide strikes a IIO tooth of theratchet-wheel It, thus moving said wheel the space of one tooth andturning the paper tube correspondingly to feed the space for one letter.When the lug leaves the shoulder of the slide, the latter is thrown backto its original position by its retracting-spring, ready to againoperate the ratchet-wheel for feeding. The space of the type-wheel,which stands normally opposite the printing-pad, is blank, and there isa pin of the series E corresponding to this space. The key correspondingto this pin is to be operated for making blank spaces in the lines ofprinting for feeding and for making margin.

As the makes and breaks of the break-wheel correspond to the letters onthe type-wheel, it will be understood that an instantaneous closing ofthe circuit occurs for every letter of the type-wheel which passes agiven point be tween the instant it starts to move and the instant it isarrested by a depressed pin, E, and a corresponding number of impulsesare sent over the line to operate a receiving-instrument at the otherend, which will be presently described.

It will be observed that the paper used is much wider than is used inordinary printingtelegraphs, and, 'as has been stated, theprinting isarranged in parallellines. The tubular paper is preferably lapped at itsedges to form a proper margin, and when after starting to print alinefrom a properpoint near one edge of the paper the operator observes theline of printing to have approached sufficiently near the other edge, heoperates a designated key, which depresses a pin corresponding to theblank space on the type-wheel in order that the wheel and connectedfeeding mechanism may be operated a sut'ticient number of times to feedthe paper around toleave a proper margin. The inclined lug at the loweredge of sleeve Q at .each revolution of the ratchet-wheel R strikes thepin q, projecting from the tubular shaft, so that the sleeve and itsarms S are driven upward as the lug rides over the pin. Asthc arms Srise upwardtheir serrations s carry the paper also upward a space properto receive a line of type, and as the sleeve and its arms fall after thelug rides over the pin, the serrations on the inner periphery of wheel Ren gage the paper and hold it up, while the arms slip down ready for anew feed.

I will now describe the receiving apparatus which is to be used at theopposite end of the line from the transmitter.

Referring to Fig. 7, the letters A and A" in dicate, respectively, thetop board and base of the receiver, the top board beingsupported bysuitable posts, 13 and 12.

Between the two front posts, 13 i is a cross-piece, 0, having a circularopening, through which is arrangeda vertical shaft, 1, having astepbearing at its lower end, while its upper end carries a type-wheel,K, andis supported in the same manner as in the transmitter. Nearitslower end the shaft I has a pinion, Z, geared with a train, L, the sameas in the transmitter, for driving the shaft 1. Upon this shaft, belowthe cross-piece O, is secured a star-wheel, V, in which is arranged toplay a double escapement pawl or anchor, V, which is secured to thearmature-lever 9 of an electro-magnet, Y. W hen this magnet isintermittently energized by rapidly successive electric impulses, thewheel V, and consequently the type-wheel on the same shaft, are allowedto have a very rapid movement under the influence of the driving-weight,but are always under control, so as to be stopped instantly when themagnet Y ceases to be active.

Through the cross-piece (3 is loosely arranged apin, E carried by alever, Fflwhich carries asmall armature, f, arranged to be attracted byan adjacent pole of the magnet Y.

When the magnet is inactive, the armature is held up by a spr1ng, f",and the tip of pin 13* then stands above the lower surface of thecross-piece C; but when the magnet is active the armature is attractedand the pin. E pro jects below the cross-piece in the path of aradialarm, M,which projects from the shaft 1, so that it will be seen that thesaid arm and the pin E effect a positive stoppage. of the type-wheelindependent of the escapement. The line L, which leads from thetransmitter, is connected to a binding-post, N, which is connected withone terminal of the magnet Y. from the other terminal of which a wire,leads to the printing-magnet, which is connected to ground by a wire,in, the sameasin the transmitter. The printing, paper-supporting, andfeeding devices of the receiver are the same as those of thetransmitter, and are similarly lettered in the drawings, and both thetransmitter and receiver are provid ed with inking-wheelsZ, for inkingthe typefaces of the'type-wheel in the usual manner. It will now beunderstood that when the trans mitter has one of its keysdcpressed forprinting and transmitting a certain letter its typewheel, as has alreadybeen explained, revolves with great rapidity until that letter isbrought opposite the printing-pad. At the same time the circuit-breakingwheel of the transmitter causes a sufficient number of rapid makes andbreaks of the circuit to cause the inagnetl. of the receiver and itsconnected devices to operate the receiver type-wheel forbringing asimilar letter opposite its printing-pad, the type-wheel of the receiverpausing exactly as the transmitter-wheel pauses, and during this pausethe printing-magnet is energized and operates the printing-pad, thefeeding for letters and lines and forming the margin. of the pagecorresponding in the receiver with the similar operations of thetransmitter. At

every closing of the circuit by the transmitter break-wheel the circuitis closed through the printing-magnet of the receiver 5 but the printing-magnet of the receiver-magnet is so adjusted that it does notoperate its printing-pad at the time the type-wheel presents the properletter in correspondence with the pause of the transmitter, when its armM strikes a depressed pin, E, and thus throws the current of theauxiliary battery on the line. \Vhen the first break of the main circuitoccurs, the receiver-magnet releases the armature f and the lever Fraises the pin E" to release the arm h to permit the shaft 1 to revolve,and when the arm M completes its revolution the magnet draws down saidarmature and projects the pin E to arrest the arm M at unison.

Having now fully described my invention, I wish it to be understood thatI do not limit myself to the precise construction and ar--,

rangement of devices as shown in my drawings, but may vary the same inany manner to better carry out the principle of my invention withoutdeparting from the true scope thereof.

What I claim is- 1. The combination, in a printing-telegraph apparatus,of a type-wheel, devices for operating the same, means, as shown anddescribed, for supporting a sheet of paper in tubular form adjacent tothe periphery of said typewheel and for feeding the paper circularlystep by step and longitudinally line by line, and the electromagneticimpression devices, all arranged and operating essentially as set forth.
